What are the security implications of not handling context switches properly in PHP?

Not handling context switches properly in PHP can lead to security vulnerabilities such as data leakage or unauthorized access to resources. To mitigate these risks, developers should ensure that sensitive data is properly sanitized and secured before and after a context switch. 

// Example of handling context switches properly in PHP

// Sanitize and secure sensitive data before context switch
$sensitiveData = 'password123';
$securedData = htmlspecialchars($sensitiveData);

// Perform context switch

// Re-validate and secure sensitive data after context switch
if(isset($_POST['input'])){
    $inputData = $_POST['input'];
    $securedInput = htmlspecialchars($inputData);
}
